l SPECIFICATION forming part of Letters Patent No. 709,406, dated September 16, 1902.

A l n Application iiled April 22,1902. Serial No. 104,117. (No model.) l

Y "To cr/ZZ whom t may concern,.-

Be it known'that we, RAYMOND H. I-IORN BROOK and WILLIAM I-I. WOODoOOK, both subjects of the King of Great Britain and Ireland,`and residents of Canton, Ohio, have invented certain Improvements in Street-(Jar` Trucks, of which the following is a speciication.

One object of our invention is to so construct a truck for street-cars that the same `can be cheaply manufactured from ordinary plates orshapes, but will be strong and rigidly braced, a further object being to so mount the car-body upon the truck that while the desired elastic support for said body will be provided the ends ofthe same will be so upheld as to prevent teetering. These Objects we attain inthe manner hereinafter set forth,

Fig. 2 isa side View of the same.

reference being had `to `the accompanying drawings, in which- Figu re 1 is a plan View of a street-car truck constructed in accordance with our invention. Fig. 3 is an i enlarged transverse section on theline a a,

Fig. 2; and Fig. 4 is an `enlarged transverse section on the line b b, Fig. 2.

The truck has Opposite sidesills 1, each of which is composed of a channel-bar with the edge flanges turned downward, the longitudi-- nal central portion of each of these sills being stienedby a depending angle-bar 2 and `the sills being connected by transverse anglebars 3 at the ends and by intermediate anglefss bars 4., the central portions of which are preferably depressed below the plane ol" the sills, as shown in Fig. 2, so as to aiord space for the brake mechanism` or other attachments i with which the under side of the body ofthe car is usually provided.

Thepedestals for the guidance of the boxes 5, which receive the journals of the axles 6, I `arecoinposed of the opposite vertical legs of SiO ayoke 7, consisting of a plate bent into yoke `forno fand having longitudinally-projecting ened and strengthened by an` angle-bar 11,

secured thereto and also secured at its upper 13 extending upwardly from this foot to the side sill l, to which it is properly secured.

The vertical brace 11, foot 12, and diagonal brace 13 can all be conveniently formed from one piece of angle-iron by suitably cutting and bending the same.

The end portions of each side sill are depressed, and these depressed portions of the side sills carry the butt-ends of quarter-elliptic springs 14, which are suitably secured to said depressed portions of the sills and support the outer ends of the bars 15, to which the corners of `the car-'body are secured, the `inner portionsi of these bars being provided with studs 16, passing through openings in the sills and having heads 17, bearing upon the upper ends of springs 19, which are'supported upon plates 20, suspended by means of rods 2l from plates 22, supported upon` the sills 1, as shown in Fig. 4. By these means the desired elastic support of the car-body is provided, the springs 14E running to the outer ends of the bars 15 and serving to prevent teetering of the car-body, which is likely to take place when such spring-supports for the corners of the saine are not provided.

The depressing of the ends of the side sills permits of the use of quarter-elliptic springs with suflicient play to answer the desired purpose.

Spreading of the lower portions of the jour- 7 and bridging the space between the peds estais, as shown in Fig. 2.

Having thus described our invention, we

claim and desire to secure by Letters Patent- Y l. A car-truck having opposite sills of chan- Ynel-iron stilfened as to their longitudinal centrai portions by means of depending anglebar braces secured to the under side of the sills, substantially as specified.

2. A car-truck having the side sills of channel-iron stiiened as to their longitudinal cen- ICO tral portions by means of depending anglebars secured to the under' sides ot' the sills, said side sills being connected by end anglebars and intermediate angle-bars, substantially as specified.l

3. A car-truck having'the side sills composed of channel-bars with transverse bars connecting the same at the ends, and intermediate transverse angle-bars connecting the side sills and bent downward into a plane below the same, substantially as specied.

4. The combination of the side sill of the truck, with journal-box pedestals composed of a bar bent into yokev form and having projecting base-flanges, and pedestal-br.tcesy each comprising a vertical leg, a foot and a `diagonal brace, the vertical leg and diagonal brace being connected at their upper ends to the sill and the foot being connected.V to the anges of the yoke, substantially as specified.

5. The combination of the side sill of the truck, with journal-box pedestal-braces each comprising avertie-al leg, a foot, and a diagonal brace, said vertical leg and diagonal brace being connected at their upper ends to the sill, and a bar or plate extending from` the foot portion of one brace to that of the other and connected to each, substantially as specied.

6. The combinationot the side sill of the truck, with journal-box pedestals composed ot' a bar bent into yoke form and having projecting base flanges, pedestalbraces each comprising a vertical leg and foot, and a di` agonal brace, the vertical leg and diagonal brace being connected at their upper ends to the sill and the foot being connected to the flanges of the yoke, and a'bar or plate extend, ing from one of said flanges to the other and connected to each, substantially as specified.

7. The combination ofthe side sills of a car-truck and the body-supporting bars at the cornersof the truck, with elastic supports for said body-supporting bars each comprising a spring for supporting the bar, a plate supporting the spring, a plate resting on the sill and a pair of'suspension-rods one on each side ot' the sill for connecting said plates, substantially as specified. v

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
